UNITED STATES JAMES GREAVES, OF WAGO, TEXAS.

Specification forming part of Letters Patent No. 190,313, dated May 1, 1877; application filed April 17, 1877.

To all whom it may concern:

Be it known that I, JAMES GREAV'ES, of Waco, county of McLennan, State of Texas, have invented certain new anduseful Improvements in Ootton Condensers; and I hereby declare the same to be fully, clearly, and exactly described as follows, reference being had to the accompanying drawings.

This invention relates to devices for cleansing and compacting cotton as it comes from the gin; and it consists in certain details of construction and combinations of parts, as hereinafter fully set forth and claimed.

As the cotton-lint is delivered from the gin it is extremely bulky, and contaminated by dust and various otherimpurities, which greatly detract from the market value of the cotton.

The object of my device is to eliminate these impurities, and at the same time to compact the cotton into an endless sheet, and thereby greatly facilitate the process of baling.

In the accompanying drawings are illustrated, in Figure l, a front, and in Fig. 2 a longitudinal vertical sectional, view of my devlce.

A represents the outer case, whichis preferably inclined, as shown, into the open end ofwhich the cotton is forced by the gin-brush, and falls upon the endless apron B. Near the end of the apron, and in close proximity to its surface, revolves the cylindrical sieve or screen 0, the shaft of which carries a gearwheel, D, which meshes with asimilar wheel, F, uponthe shaft, which drives the apron B.

Above the cylindrical screen is situated a fan-blower, G, having a suitable dischargespout, H. The upper part of the case is furfurnished with a hinged lid, a, in order to give access to the interior of the case, and a small sliding door is arranged opposite the screen for a similar purpose.

The operation of the device is as follows: The lint, being delivered into the open end of the case, is carried forward by means of the revolving apron to the screen. A strong current of air is induced by the fan-blower up ward through the revolving screen, whereby the dust is eliminated from the lint, and passes out at the mouth of the blower. In its passage between theapron and the screen the cotton is compacted into a thin sheet-a form very convenient for baling--and is practically freed from dust and impurities.

The bearings of the apron-shaft areslotted, as shown at b, in order to raise or lower the apron, and thus regulate the thickness of the sheet of. cotton, as may be desired.

The screen should revolve at about the same speed as the apron, and to this end the number of cogs upon their driving-wheelsshould be as the radius of the screen to the radius of the apron-shaft.

In the drawings the fan-shaft is shown as having a pulley for the attachment of a belt; but the fan may also be driven by means of a train of cog-wheels gearing with the wheel D.

The main driving-power is applied to any one of the shafts in any convenient way.

Some of the advantages attending the use of my device may be briefly mentioned. The

cotton being compacted into an endless bat greatly facilitates the process of baling, enabling a greater weight of cotton to be compressed into a given bulk; and the sample is rendered more uniform than by the present method, thus preventing mixed packed bales.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a cotton-condenser, the combination of an endless apron, a revolving screen, and a fan-blower, all arranged substantially as described.

2. In combination with the screen 0, the apron B, having slotted bearings b, substantially as described, and for the purpose set forth.

3. The case A, having lid 00, in combination with the apron B, screen 0, and fan G, substantially as described.
